The married couple of Danny and Tiffany Preston are Rainbow Arabia, a project fairly named for its filtration of Middle Eastern-rooted music through a prism of computerized sonic tics and tatters. Tiffany’s yips and chants are essentially indecipherable on “Omar K,” which leaves a lot of latitude for video interpretation. I can’t imagine the song was intended to tackle demonic transformation, grocery store line dances, or cleanups in aisle 9, but the goofy “Come To Daddy” meets “Been Caught Stealing” video treatment wraps the cut’s African-guitar spiked electro in some unexpected levity. Curveball.
